Okay so i tested my sawed off FX maverick today ( 700 to 600 mm )
And i will have to admit so far not a success, clearly i have a issue as groups are erratic, with a few really bad " fliers "
SO as i am not the surrendering kind, i have restored both barrels to a clean end, and i am now ready to proceed with trying ghetto crowning once again, and this time i will try others solutions VS the one i came up with myself.
Not able to blame my groups on the weather, it was excellent range weather.
Still think it is a crown issue VS saying that a FX barrel with no choke are not at all able to shoot, i am quite sure it should at least be able to shoot better than what i saw today, i just have to do a better job.
PS: i have looked at prices for a 600 mm Heavy barrel, but i would prefer to save those money for other things.
PPS. when not throwing erratics the STD FX liner was able to put dents / holes in a Metal plate 134 yards away and within acceptable distance of aim ( 2 " ), but it for sure was a POI chase.

well i new lead in i am not able to do without a lathe,,,,, and me figuring out how something like that should look in a airrifle.
I have seen in rifles you can get a reamer for various ammo, but not sure you get that for airguns, and even so probably too expensive.
Just wanted to see if loosing the choke would make changes CUZ the CZUB barrel on my Two ( no choke ) can / will shoot 16 grain slugs just fine, with pretty much same twist rate as FX barrels in .177 ( 1:17.7 )
Also some i have seen shoot FX Heavy barrels and 16 grain just fine, but i have tried like +1000 16 grain rounds in my not modified 700 mm Maverick and not been able to make that work.
Mind you, i am not lucky with barrels, Maverick was bummer in original 600 mm, and the first barrel on my Two the 700 MM LW barrel, had a massive choke in the middle 30 % of a barrel that was supposed to have 0 Choke.

My Maverick are originally 600 mm, but as it came with a horrible barrel i changed to 700 mm when that became possible, and then the rifle worked just fine.
Cut off choke to maybe make the Maverick able to shoot heavier .177 slugs, CUZ as is i can only get 13 grain to fly well and 16 not bad but still not something i would shoot daily.
Cutting breech end would be a big mistake, not least as i do not have access to a lathe CUZ then i would not have this issue i think.
All out experiment here, i am also way past the FX rifle, but still like to play around, in the end i might have to buy a new Heavy barrel, and then donate the rifle to someone, probably my nephew.
